Answer:
According to the image, the approximate QT interval is 0.4 seconds.
Explanation:
The QT interval is the space between the beginning of the QRS complex and the end of the T wave, which represents from the beginning of depolarization to ventricular repolarization.
Considering that the extandardized measurements of an EKG, where the paper circulates at a speed of 25 mm/s, 1 mm horizontal —measuring time— has an equivalence of 0.04 s.
In the image, there is 10 mm between the beginning of the QRS and the end of the T wave, so:
0.04 seconds X 10 mm = 0.4 seconds.
Then, the estimated QT interval is 0.4 seconds.

Introns because they are coding sequences.
Exons because they are non-coding sequences.
The process of sexual reproduction involves two parents, each contributing one gamete. Gametes are produced
by a process called meiosis, which starts by the duplication of the
chromosomes, followed by two rounds of cell divisions and halving of the
chromosome number. Gametes have half the chromosome number of other
adult
cells of an organism.
A key feature of meiosis is the exchange of chromosome pieces which occurs in the first division of this process, called recombination or
crossing over. Recombination is a very important source of genetic
variation between individuals of sexually reproducing species, and the
driving force for the process of natural selection.
